an idiot's dance

A young woman in a striped shirt and black pants stands in a room with wooden furniture, performing a dance move where she extends her arms and then brings her hands together in front of her chest. As she moves, text appears on screen, first saying "PPAP," then "I have a pen," followed by "I have an apple," and finally "Ah apple pen," with a visual effect of a flame-like trail appearing as she mimics writing and then holding an imaginary apple and pen.
